title: Rapid construction of [5-6-7] tricyclic ring skeleton of Calyciphylline alkaloid daphnilongeranin B.
abstract: A concise photochemical [2 + 2] cycloaddition-Grob fragmentation sequence sets the common tricyclic ring skeletons of the Calyciphylline A-type alkaloids, particularly those in daphnilongeranins, daphniyunnines, and daphniglaucins.
